Member Operations Research Faculty

(Ph.D., Economics, University of Wisconsin, Madison)

Dr. Weaver's current research focuses on microeconomic and econometric analysis of public policy targeted at the performance of agricultural production and marketing systems. Recent studies have had one of two focuses: 1) time series studies of the operation of frequently traded goods to evaluate arbitrage opportunities, risk, and efficiency of transmission of information concerning levels of price and volatility; and 2) the levels and management through contracting of agricultural impacts on water quality, agricultural policy and regulatory impacts on productivity, and the contribution of research to the productivity, profitability and competitiveness of U.S. agriculture. Most recent grants have funded research on the use of contracting to manage price risk and quality in food supply chains.  

Dr. Weaver has served as Senior Project Officer at the National Academy of Sciences, National Research Council, Board on Agriculture, and a visiting scholar at I.N.R.A./Rennes Toulouse (France); Catholic University, Louvain-La Nerve (Belgium); Wageningen Agricultural University (Netherlands).  He has consulted extensively with the World Bank, U.S. Senate Agriculture Committee, and other government agencies as well as private corporations.  Dr. Weaver recently was a member of a team that won the AAEA National Award for Distinguished Extension program.
